MLPA and Sanger sequencing confirmed these two variants and showed the same genotype of a paternally inherited c.3717+5G&gt;A and a maternally inherited EX1_2DEL variation in both the proband and his affected sister. The minigene assay verified the pathogenicity of c.3717+5G&gt;A and indicated that this variant possibly caused abnormal splicing, resulting in jump of exon 27 and retention of 51\u2009bp at the 5\u2032 end of intron 27, leading to the formation of abnormal proteins.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>\n                      This study reports a novel pathogenic variant c.3717+5G&gt;A of\n                      <jats:italic>PCDH15<\/jats:italic>\n                      in a proband for the first time.
